Vapor Adaptor Cap

304 4" Vapor Recovery Cap

The vapor cap secures the vapor check valve preventing dust and debris buildup. It also protects the vapor poppet of a dual point fill system. Orange in color to indicate vapor recovery lines and lockable to prevent misuse, our vapor cap fits all 4" male quick couplings. The cam action creates a solid push down and pull up movement for fast, easy removal and replacement of cap.
